Question

Solve the following equation for x. 1/5x + 3x = 2x + 42 V =

Answer 1

Solve for x:

`\begin{gathered} (1)/(5)x+3x=2x+42 \\ (1)/(5)x+3x-2x=42 \\ ((1+3\cdot5-2\cdot5)/(5))x=42 \\ (1+15-10)/(5)\cdot x=42 \\ (6)/(5)x=42 \\ x=42\cdot(5)/(6)=(210)/(6)=35 \end{gathered}`

The value of x is x=35.
